Morphing with Lines

Morphing between two images I0 and I1 is done as follows.

Lines are defined on the two images I0 and I1

The Mapping between the lines is specified

Depending on the number of intermediate frames required, a set of interpolated lines are obtained

An intermediate frame is obtained by doing three things

The lines in the first image I0 are warped to the lines corresponding to the intermediate image

The lines in the second image I1 are warped to the lines corresponding to the intermediate image

The two warped images are now combined proportionately depending on how close the frame is with respect to the initial and final frames

Since the images have been warped to the same shape before cross-dissolving the intermediate image looks good.

An example of a morph process is shown below.

The two original images, the two warped images and the two images corresponding to a cross-dissolve of the original images and a cros-dissolve of the warped images are shown.
